When there's need to make a 4ch capture topology would TEST_PDM_ACTIVE be set to 2 and the PDM_TUPLES macro arguments be duplicated with another 0110000 (where the "1" values are mic enables)? Or is this function OK as such to use with any value of TEST_PDM_ACTIVE within HW capability limits and as long as both microphones of a stereo PDM controller are used?
Creating a mono single microphone capture topology obviously needs a new test test-capture.m4 macro version.
Seppo, is this something we can do this incrementally ? I can apply the series if it's OK by you ? or would you and Ranjani like a V5 ?
I've reviewed all new DMIC related patches and on my behalf I recommend to apply the v4 set.
This question was about making test pipelines and it's now clear how the number of channels is customized in the topology m4 notation. We will contribute later more examples with different number of channels and capture sample rates.
Thanks, Seppo
